          Tombs at Hsingchuang, Chihli, near Peking. The nuts are of medium 
size and are fairly good to eat. The species is of interest at this 
time owing to the fact that it has been found slightly resistant to 
the chestnut blight.

56768. CASTANEA sp. Chestnut. From Yunnan, China. Collected by 
J. F. Rock, Agricultural Explorer. This lofty tree, 80 to 100 feet 
tall, with trunks 3 feet in diameter, is found in the pine forests of 
the Shweli Valley, at altitudes of about 6,000 feet. The burs are in 
long densely packed spikes and the involucres are covered with long, 
soft, green spines. The small nuts are solitary or in twos. This is 
one of the finest forest trees of Yunnan and, according to natives, 
the wood is durable and never attacked by insects.

Rock, Agricultural Explorer. A splendid forest tree of the Likiang 
valley where it grows at altitudes up to 9,400 feet. It often attains 
80 feet in height, with a trunk 4 feet in diameter. The large 
clusters of pinkish purple flowers appear in early spring. The hard

J. F. Rock, Agricultural Explorer. A tree, 50 to 80 feet high, which 
has been domesticated by the Chinese around Talifu, Yunnan, where it 
is called Mu kua. The very aromatic fruits, rich yellow with a reddish 
tinge, have firm yellow flesh; they make jelly and preserves 
closely similar to those prepared from the common quince.

CHAYOTA EDULIS. Chayote. From Mexico, Central America, and the 
West Indies. A vigorous-growing, perennial-rooted vine, suited to the 
Southern States. The plant yields enormous crops of fruits that keep 
well and are more delicately flavored than the squash. The freedom 
from fiber, the fine texture, and the ease of its preparation for 
cooking render the chayote adaptable for use in a variety of delicious 
dishes. The fruits may be fried, creamed, stuffed, served in stews, 
baked with meats, pickled, or preserved. Special directions for growing 
and cooking will be forwarded on request.

deciduous ornamental tree bearing in spring a multitude of white, 
deliciously fragrant flowers with handsome fringed petals, followed in 
the fall by masses of blue berries resembling wild grapes. This tree is 
used by the Chinese as a stock on which to graft their scented olive, 
Osmanthus fragrans.
